Originally assumed to be a reborn version of the believed deceased Atomic Esquire, he acted as a ruthless enforcer of chivalrous code up until he was exposed by the real Atomic Esquire who revealed eXtreme to be a clone placed by Doctor Science to besmirch Atomic Esquire's image, eXtreme dropped his act and has since taken the role of a common brute. Having been summoned to present times by his master, Doctor Science, eXtreme currently serves as one of the Sageworthy Society's many enforcers.

Atomic eXtreme is capable of superhuman feats of strength, augmented by cybernetic implants. Both his left arm and leg are prosthetic limbs capable of delivering devastating attacks. It is unknown if he has any other noteworthy powers, or if he simply doesn't have the presence of mind to use them.

Unlike his heroic counterpart, Atomic eXtreme does not have any unique equipment. He simply uses any nearby weapons to savagely beat on his opponents.
